Description

A kind of tunnel counter-slope draws water purifier and its control method and purification method

Technical field

The present invention relates to tunnel counter-slope technical field of drainage, relate in particular to a kind of tunnel counter-slope draw water purifier and Its control method and purification method.

Background technology

Build center of gravity with traffic and Hydraulic and Hydro-Power Engineering to the extremely complicated western mountainous areas of topographic and geologic condition and karst Area transfer, will appear from a collection of thering is " great burying, Chang Dongxian, heavily stressed, strong karst, high hydraulic pressure, construction are complicated, disaster takes place frequently " Etc. the profound Tunnel Engineering of the excessive risk of distinguishing feature.In highway communication field, profound tunnel is the throat of traffic engineering, is relation Lifeline engineering to society and Development of Economy.In the last few years, the technological challenge being brought by the construction of distance counter-slope is further Substantially, the construction time geological disaster such as gushing water retention of excessive fluid thus resulting in continuously emerges, such as: Hubei expressway from Shanghai to Chendu homogeneous kernel tunnel Outlet paragraph in road is constructed due to counter-slope, meets with large-scale retention of excessive fluid accident when passing through manger hole underground underground river and super large tomography, due to Drainage system is limited in one's ability, leads to the barrel more than 700m to be submerged, and, more than 1 year, economic loss is serious for construction delay.Hubei Shanghai Rong's western highway Longtan Tunnel port of export is the construction of distance counter-slope, meets with when passing through the fault belt of 700m length and gushes mud Retention of excessive fluid, plumbing brings huge difficulty.In railway territory, to be most difficult to the mountain railway built in the world -- Yichang-Wanzhou Railway is Example, there is the counter-slope construction paragraph of relatively long distance in its Maluqing tunnel, successively occur 19 serious gushing waters to dash forward mud calamity in construction Evil, moment dash forward water yield create world's railway construction, on January 21st, 1 is especially big twice with April 11st, 2008 The prominent mud disaster of gushing water leads to 15 people dead altogether.And Wuqiaoling tunnel there is also the counter-slope construction area of longer paragraph in construction, Design for drainage system brings huge challenge.

The disaster that retention of excessive fluid brings from the foregoing, it will be observed that dashing forward in tunnel is of common occurrence, how to be just avoided that the generation of these accidents？When When prominent retention of excessive fluid occurs, fast and effectively water-pumping/draining operation, it can be avoided that Accidents Disasters occur, reduces unnecessary personnel and economy is damaged Lose it is ensured that the normal construction in tunnel.On the construction equipment and conceptual design of draining, an efficient pumping plant pump drainage water system, Often determine water-pumping/draining construction one-tenth with lose, also contribute to the safety in production of engineering project.

Current tunnel drainage pumping plant technology has " a kind of drainage arrangement of distance reverse-slope tunnel and water discharge method " (201210112312.2), the method arranges a precipitation cavern and a pumping plant cavern in every one-level simultaneously, to avoid pipeline The blocking being led to due to dirt accumulation, but due to will excavate Liang Ge cavern, workload is big, relatively costly；" cable tunnel is arranged automatically Water system " (200810137337.1) arranges multiple water-level probes on sump, but catchments when reaching high water level, starts diving Pump carries out draining, but the method is directed to the drainage effect of the little water yield preferably, for big yield, for a long time monitoring row in tunnel Water is simultaneously inapplicable；" a kind of experimental provision of simulation Limestone pavement tunneling drain calcium carbonate crystal rule " (201410484203.2) Provide a kind of experimental provision of function admirable, improve shelf life and the reliability of Limestone pavement tunnel drainage system, but its Only calcium carbonate crystal is studied, specific aim is stronger, is not applied for other lithology tunnels；" a kind of super long tunnel is used Drainage system " (201220694226.2) first with water pump, the water in tunnel is extracted in the sump in inclined shaft, then by collection Water pump in well pulls water out outside hole, ignores tunnel mud stopping state；" a kind of tunnel props up hole counter-slope drainage system " (201420630003.9), by the silt during setting setting pot reduces water-pumping/draining below sump it is ensured that water pump Work, shortcoming is that setting pot increased excavation construction amount, if setting pot mud is piled up excessively, because its depth is larger, no simultaneously Easily desilting.

In general, existing drainage equipment has a following Railway Project at present:

1. pumping for water pump blockage.Because, during constructing tunnel, water, during collecting, can carry substantial amounts of Carg or rubbish incidental, easily block pumping for water pump pipe during pumping for water pump, cause water pump water-pumping/draining operation to lose Effect；Build setting pot according to conventional method, then can increase construction cost and workload, cost is higher, therefore needs proposition one badly Plant the water-pumping/draining technology that can be prevented effectively from pump mouth blocking；

2. drainage effect gets half the result with twice the effort.Current tunnel drainage facility needs assistant director to manage, and when carrying out draining, needs to arrange Water assistant director judge to water yield, then Non-follow control water pump carries out draining, and its mobility is poor, when running into emergency case, no Draining and early warning can fast and effectively be carried out, be easily caused generation situations such as tunnel is flooded.Now need badly and develop one kind certainly Dynamic water-pumping/draining and water yield source of early warning；

3. water resource waste.In the work progress in tunnel, from work surface drill two lining construction, or even tunnel watering control Airborne dust processed, is required for diversion from hole, if waste water in tunnel sump can be carried out evolution process, reuses, can not only Enough saving water resources, also can reduce the cost of transportation of water resource；Therefore need development one kind badly and can carry out original position Water warfare and utilization Device.
